Definitions

  • esterquats as microbicidal agents
  • the invention is in the field of cationic surfactants and relates to the use of mixtures of esterquats and partial glycerides as active microbicides.
  • Microbicidal agents are usually used to prevent or completely kill microorganisms. So far, quaternary ammonium compounds such as benzalkonium chloride or cetyltrimethylammonium chloride have proven their worth as microbicidal active ingredients. However, it has been shown that such compounds are difficult to biodegrade in the sewage treatment plant. Accordingly, there is a need for compounds having a microbicidal action which are comparable in their performance to the quaternary ammonium compounds, but have a significantly improved biodegradability.
  • quaternary carboxylic acid alkanolamine ester salts are known as microbicidal active ingredients which are prepared by reacting 2-dimethylamino-2-methyl-1-propanol with fatty acids and subsequent quaternization.
  • these compounds show little activity against the gram-negative bacterium Pseudomonas aeruginosa, which is disadvantageous in view of the frequently occurring water germ, which in particular leads to product contamination.
  • European patent application EP 0 461 419 describes poly (oxyalkylene) aminoalkanol esters and their ammonium compounds, which are also said to have a microbicidal action. However, these compounds necessarily have at least one hydroxyisopropyl radical and carry a methyl group on the nitrogen atom. No information is given on the effectiveness of these compounds against bacteria, in particular against the frequently occurring bacterium Pseudomonas aeruginosa.
  • German patent application DE 19742222 A1 describes short-chain quaternary carboxylic acid alkanolamine ester salts as microbicidal active ingredients.
  • the object of the present invention was to provide microbicidally active compounds which, in their microbicidal activity, correspond to those of the conventional quaternary ammonium compounds. fertilize are comparable. Above all, the compounds should also have a microbicidal action against the frequently occurring bacteria Pseudomonas aeruginosa, Staphylococcus aureus and Candida albinans. Furthermore, the compounds should be more biodegradable than the conventional quaternary ammonium compounds.
  • the invention relates to the use of esterquats selected from the group formed by
  • R 1 CO for an acyl radical with 16 to 30 carbon atoms
